Im getting error code 16825 EVAP emission control system: incorrect flow, lower limit exceeded.
Most common thing is N80, or purge valve which i have replaced, but after a few days the MIL light is back on.
I have read on forums elsewhere that this can be caused by leaking evap pipe work, or even a dodgy cap seal on the tank. How can I pressurise the system to find a leak.
I have also looked at block 070 and 071 with VAG-COM. It shows you the flow rate and valve opening %age, but the flow rate never changes its stuck at about 20%, minimum should be about 50% from what i can make out.
